Less than 24 hours after a screening in Madrid, Tom Cruise was back in fine form today for his London premiere of Mission: Impossible — Ghost Protocol. He signed autographs and posed for photos with fans before hitting the red carpet. Tom walked the press line solo then joined up with his costars Paula Patton and Simon Pegg. Tom met with Spanish royalty during yesterday's stop, but it appears one of Prince William and Harry's relatives made it out for this evening. Tom's international tour continues tomorrow with a stop in Brazil, and he'll bring the spy thriller to NYC Monday. He's finishing out the year on a high note with Mission Impossible already getting an enthusiastic reception from stars like Ryan Seacrest. Next year is shaping up to be another big one for Tom with his highly anticipated musical, Rock of Ages, slated for a June release.
